oracle监听启动时报TNS-00507问题解决一例

Linux系统中，启动oracle监听的时候报如下错误：

[oracle@centos ~]$ lsnrctl start LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 17-APR-2010 00:25:22 Copyright (c) 1991, 2005, Oracle. All rights reserved. Starting /u01/app/oracle/product/10.2.0/db_1/bin/tnslsnr: please wait... TNS-12537: TNS:connection closed TNS-12560: TNS:protocol adapter error TNS-00507: Connection closed Linux Error: 29: Illegal seek

[@more@]

经过检查，发现hosts文件，内容如下：

[root@centos ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. ::1 localhost.localdomain localhost 192.168.19.219 centos

缺少了 127.0.0.1 localhost行，加上这行后，如下所示，监听就可以正常启动了。

[root@centos ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. ::1 localhost.localdomain localhost 127.0.0.1 localhost 192.168.19.219 centos
